CoStar Group Third Quarter 2021 Revenue Increased 17% Year-over-Year, CoStar Accelerated to Double-Digit Revenue Growth with Net Sales Reaching All-Time High

October 26, 2021

WASHINGTON--(BUSINESS WIRE)-- CoStar Group, Inc. (NASDAQ: CSGP), the leading provider of commercial real estate information, analytics, and online marketplaces, announced today that revenue for the quarter ended September 30, 2021, was $499 million, an increase of 17% over revenue of $426 million for the third quarter of 2020.

Net income for the third quarter of 2021 was $64 million, or $0.16 per diluted share. Non-GAAP net income for the third quarter of 2021 (which excludes amortization of acquired intangible assets, stock-based compensation, and other items as described below) was $99 million or $0.25 per diluted share, an increase of $10 million or 11% versus the third quarter of 2020. EBITDA for the third quarter of 2021 was $123 million, an increase of 13% versus EBITDA of $108 million for the third quarter of 2020.

“We achieved another great quarter of strong results, with CoStar Group now at nearly $2 billion in run rate revenue and profit for the third quarter of 2021 well-ahead of our guidance,” commented Andrew C. Florance, Founder and Chief Executive Officer of CoStar Group. “CoStar performance continues to improve, with revenue returning to double-digit growth rates in the third quarter of 2021 and our CoStar sales team produced net sales bookings 57% higher quarter-over-quarter and 566% higher year-over-year," continued Florance. "I’m very happy with the performance of our Ten-X and Residential businesses as well, both of which delivered exceptional revenue growth of 27% for Ten-X and 38% for Homesnap, on a year-over-year and pro forma basis, respectively.”

“With recent record levels of demand for apartments, vacancies have declined to the lowest levels in decades creating some headwinds for demand in apartment advertising. However, traffic to our network of sites increased 17% year-over-year in the third quarter of 2021,” stated Florance, “with Apartments.com generating millions more high-quality leads for our customers year-over-year in a low-vacancy environment while our clients are increasing their rents to record levels. This tremendous growth in leads and rents has positioned Apartments.com to begin initiating pricing adjustments to better capture the value of the lead flow we are delivering to our clients. We are just beginning to implement the new pricing, and I am encouraged by the initial results of the price changes.”

Companywide net bookings for the third quarter of 2021 were $47 million, which includes stronger than expected CoStar sales offset by sales results slowed by the ultra-low vacancy rates in Multifamily.

As of September 30, 2021, the Company had approximately $3.8 billion in cash, cash equivalents and restricted cash and outstanding debt of approximately $988 million.

2021 Outlook

“In order to provide additional transparency and insight into the revenue performance of our most promising growth areas, we will now report revenue for both LoopNet and Residential services separately in our quarterly financial results,” said CoStar Group Chief Financial Officer, Scott Wheeler. The Commercial Property and Land sector is being renamed Other Marketplaces and includes Ten-X and the Lands and Businesses for Sale marketplaces.

The Company is adjusting its revenue guidance for the full year of 2021 to a new range of $1.935 billion to $1.940 billion, representing growth of approximately 17% year-over-year at the midpoint of the range. The new guidance includes a reduction in expected revenue from Multifamily which is partially offset by stronger expected revenue from CoStar. Revenue for the fourth quarter of 2021 is expected to be in the range of $498 million to $503 million, representing year-over-year revenue growth of approximately 13% at the midpoint of the range.

The Company is raising its adjusted EBITDA guidance for the full year of 2021 to a new range of $615 million to $620 million, representing growth of approximately 12% at the midpoint of the range. For the fourth quarter of 2021, the Company expects adjusted EBITDA in a range of $161 million to $166 million.

The Company is raising its non-GAAP net income per diluted share guidance for full-year 2021 to a new range of $1.07 to $1.08 per share based on 394 million shares. For the fourth quarter of 2021, we expect non-GAAP net income per diluted share in a range of $0.29 to $0.30 per share based on 394 million shares. These ranges include an estimated non-GAAP tax rate of 25% for the full year and the fourth quarter of 2021.

The preceding forward-looking statements reflect CoStar Group’s expectations as of October 26, 2021, including forward-looking non-GAAP financial measures on a consolidated basis, based on current estimates, expectations, observations, and trends. Given the risk factors, rapidly evolving economic environment, and uncertainties and assumptions discussed in this release and in our quarterly reports on Form 10-Q and annual reports on Form 10-K, including uncertainties as a result of the COVID-19 pandemic and responses to it by, and the impact on, global economies and the commercial real estate industry, actual results may differ materially. Other than in publicly available statements, the Company does not intend to update its forward-looking statements until its next quarterly results announcement.

Reconciliation of EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share to their GAAP basis results are shown in detail below, along with definitions for those terms. A reconciliation of forward-looking non-GAAP guidance to the most directly comparable GAAP measure, net income, can be found within the tables included in this release.

Non-GAAP Financial Measures

For information regarding the purpose for which management uses the non-GAAP financial measures disclosed in this release and why management believes they provide useful information to investors regarding the Company’s financial condition and results of operations, please refer to the Company’s latest periodic report.

EBITDA is a non-GAAP financial measure that represents GAAP net income attributable to CoStar Group before interest (expense) income and other (expense) income, loss on debt extinguishment, income taxes, depreciation and amortization.

Adjusted EBITDA is a non-GAAP financial measure that represents EBITDA before stock-based compensation expense, acquisition- and integration-related costs, restructuring costs, and settlements and impairments incurred outside the Company’s normal course of business.

Non-GAAP net income is a non-GAAP financial measure determined by adjusting GAAP net income attributable to CoStar Group for stock-based compensation expense, acquisition- and integration-related costs, restructuring costs, settlement and impairment costs incurred outside the Company's normal course of business and loss on debt extinguishment, as well as amortization of acquired intangible assets and other related costs, and then subtracting an assumed provision for income taxes. In 2021, the Company is assuming a 25% tax rate in order to approximate our statutory corporate tax rate excluding the impact of discrete items.

Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP net income per diluted share. For periods with GAAP net losses and non-GAAP net income, the weighted average outstanding shares used to calculate non-GAAP net income per share includes potentially dilutive securities that were excluded from the calculation of GAAP net income per share as the effect was anti-dilutive.

Earnings Conference Call

Management will conduct a conference call to discuss third quarter 2021 results and the Company’s outlook at 5:00 PM EDT on Tuesday, October 26, 2021. A live audio webcast of the conference will be available in listen-only mode through the Investors section of the CoStar Group website: https://investors.costargroup.com. A replay of the webcast audio will also be available in the Investors section of our website for a period of time following the call.
